Data Sheet
| Amino acid sequence | NSNTGCPPSY DGYCLNGGVC MYVESVDRYV CNCVIGYIGE RCQHRDLRWW KLR. |
| Biological Activity | The ED50 as calculated by the dose-dependant proliferation of murine BALB/c 3T3 cells is less than 0.1ng/ml, corresponding to a specific activity of > 10,000,000 units/mg. |
| Description | Epidermal Growth Factor Rat purified from submandibular gland is a single, glycosylated, polypeptide chain having a molecular mass of 6.15 kDa.The EGF is purified by proprietary chromatographic techniques. |
| Expression host | Adult Male Rat Submandibular Glands. |
| Formulation | The protein was lyophilized from a concentrated (1mg/ml) solution containing 0.01M sodium acetate buffer. |
| Protein Background | Epidermal growth factor has a profound effect on the differentiation of specific cells in vivo and is a potent mitogenic factor for a variety of cultured cells of both ectodermal and mesodermal origin. The EGF precursor is believed to exist as a membrane-bound molecule which is proteolytically cleaved to generate the 53-amino acid peptide hormone that stimulates cells to divide.EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. |
| Purity | Greater than 99.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| Reagent Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Solubility | It is recommended to reconstitute the lyophilized Epidermal Growth Factor in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized Epidermal Growth Factor Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution EGF should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Synonyms | Urogastrone, URG, EGF. |
